NAME¶
Net::Frame::Layer::IPv6::Routing - Internet Protocol v6 Routing Extension Header
layer object
SYNOPSIS¶
use Net::Frame::Simple;
use Net::Frame::Layer::IPv6::Routing;
my $icmp = Net::Frame::Layer::IPv6::Routing->new(
nextHeader => NF_IPv6_PROTOCOL_TCP
hdrExtLen => 2
routingType => 0,
segmentsLeft => 1,
reserved => 0,
addresses => ['::1']
);
#
# Read a raw layer
#
my $layer = Net::Frame::Layer::IPv6::Routing->new(raw => $raw);
print $layer->print."\n";
print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
if $layer->payload;
DESCRIPTION¶
This modules implements the encoding and decoding of the IPv6 Routing Extension
Header layer.
RFC:
ftp://ftp.rfc-editor.org/in-notes/rfc2460.txt
See also
Net::Frame::Layer for other attributes and methods.
ATTRIBUTES¶
- nextHeader
- Protocol number of the next header after the Routing header.
- hdrExtLen
- The length of the Routing header in 8-byte units, not including the first
8 bytes of the header. For a Routing Type of 0, this value is thus two
times the number addresses embedded in the header.
- routingType
- This field allows multiple routing types to be defined; at present, the
only value used is 0.
- segmentsLeft
- Specifies the number of explicitly-named nodes remaining in the route
until the destination.
- reserved
- Not used; set to zeroes.
- addresses
- A set of IPv6 addresses that specify the route to be used.
The following are inherited attributes. See
Net::Frame::Layer for more
information.
- raw
- payload
- nextLayer
METHODS¶
- new
- new (hash)
- Object constructor. You can pass attributes that will overwrite default
ones. See SYNOPSIS for default values.
- computeLengths
- Computes hdrExtLen and segmentsLeft based on number of
addresses.
- computeSegmentsLeft (0 | 1)
- Disable (0) or enable (1) automatic computing of segmentsLeft by
the computeLengths method. Default is enabled.
The following are inherited methods. Some of them may be overridden in this
layer, and some others may not be meaningful in this layer. See
Net::Frame::Layer for more information.
- layer
- computeLengths
- computeChecksums
- pack
- unpack
- encapsulate
- getLength
- getPayloadLength
- print
- dump
